Full details

The Helly Hansen Cascais Trunk is a versatile 4.5-inch swim short designed for active adults who prioritize comfort and functionality during water-based activities like sailing and swimming. Constructed from a lightweight, quick-drying polyester blend with added stretch, these shorts offer excellent mobility and all-day comfort. While perfect for high-intensity movement, users should note that the 4.5-inch inseam is shorter than traditional board shorts, which may be a consideration for those who prefer more leg coverage.

FAQs

Are these trunks true to size?

Yes, they feature a regular fit that aligns with standard adult sizing, supplemented by an elastic waist for extra comfort.

Can I use these for general exercise outside of water?

Absolutely. The quick-drying, stretchy material makes them excellent for hot-weather gym sessions or outdoor sports.

Do the pockets have zippers?

No, these pockets are standard slip-in style pockets designed for convenience, not for securing valuables in the water.

How short is a 4.5-inch inseam?

A 4.5-inch inseam generally sits well above the mid-thigh, offering a shorter, athletic look similar to performance swim shorts.

Is the liner removable?

The liner is integrated into the construction of the short for support and is not intended to be removed.

What material are the shorts made of?

They are constructed from a performance polyester blend designed for durability, stretch, and moisture management.

Troubleshooting

Fabric remains damp for too long

Ensure the garment is not bundled up; hang it in a well-ventilated area to maximize airflow.

Drawstring feels difficult to tighten

Check for salt crystallization around the eyelets and rinse the area with warm fresh water to clear debris.

Setup, Compatibility & Care

To ensure the longevity of your Cascais Trunks, rinse them thoroughly with fresh water after every use in salt or chlorinated water to remove corrosive minerals. When washing, use a gentle cycle with cold water and avoid heavy bleaches or fabric softeners, which can degrade the elastic properties of the fabric. Always hang-dry the shorts away from direct, harsh sunlight to prevent fading. The regular fit is designed to be true-to-size, though the elastic waist offers flexibility if you fall between standard sizing increments.
